Detailed Product Description

Four Seasons 33344 is a steel filter drier designed for automotive air conditioning systems that require a 3/8 in. inlet and 3/8 in. outlet with O-ring connections. The body measures 2.500 in. in diameter and 10.000 in. in length, and the unit includes green O-rings for sealing. As an A/C receiver drier, it helps manage moisture and refrigerant cleanliness in the HVAC circuit.

Compatible fitment includes 1977-1980 Lincoln Versailles and 1976-1980 Mercury Monarch, including factory air configurations noted for those vehicles. If you are replacing a worn or contaminated receiver drier on a Lincoln Versailles or Mercury Monarch, Four Seasons 33344 provides the correct connection style and dimensions for the listed applications. This part cross-references UAC RD4127C and Pioneer Automotive Industries 603343 for the same application.

What It Helps Address

• Moisture buildup in the A/C system
• Reduced refrigerant flow caused by a saturated drier
• Seal leakage at receiver drier connections
• Service issues on factory air HVAC systems
• Replacement needs after A/C component repair or compressor service

Installation Notes and Tips

Verify inlet and outlet connection style, body length, and mounting arrangement before installation. This unit is listed with a bracket configuration, but a mounting bracket is not included. Replace O-rings during service, evacuate the system properly, and confirm refrigerant charge and leak-free operation after installation. For best results, install the receiver drier any time the A/C system has been opened for major repair.

Quality Assurance

Four Seasons 33344 is a new replacement part that meets or exceeds OEM requirements. The Four Seasons Filter Drier line is built for service applications where correct fit, sealing, and moisture control are critical to HVAC performance.
